본 발명은 석분(石粉)이 혼합된 합성수지 복합재료 및 그 제조방법에 관한 것으로, 화강암이나 현무암 등의 자연석 분말과 불포화폴리에스테르수지(不飽和 polyester 俊脂)를 구조체 형성의 주 재료로 하고, 여기에 산화마그네슘, 백탄(白炭) 등의 기능성 분말을 첨가함으로써 성형성 및 생물친화성이 뛰어난 복합재료를 얻을 수 있도록 한 것이다.BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a synthetic resin composite material in which stone powder is mixed and a method for manufacturing the same, wherein natural stone powder such as granite or basalt and unsaturated polyester resin are used as main materials for forming a structure. Functional powders such as magnesium oxide and white charcoal are added to the composite material to provide excellent moldability and biocompatibility.

합성수지 복합재료는 강도에 비하여 경량화가 용이하고, 가격이 저렴할 뿐 아니라 성형성 또한 뛰어나 각종 생활용품은 물론, 산업용 구조재 및 건축자재 등 다양한 용도로 활용되고 있다.Synthetic resin composite material is easy to lighten compared to the strength, low cost and excellent moldability, and is used for various applications such as industrial structural materials and building materials as well as various household goods.

그러나 이러한 종래의 합성수지 복합재료는 주로 합성피혁형태의 직물복합체 또는 섬유보강플라스틱(FRP)이 주종을 이루는 것으로, 천연소재와 그 물리, 화학적 특성은 물론, 외관이나 질감에 있어서도 큰 차이를 가지고 있어서, 고급제품에 적용되기가 매우 어려웠을 뿐 아니라, 각종 유해물질을 함유하고 있어서 건강을 중시하는 소비자들로부터 외면을 받아온 것이 사실이다.However, the conventional synthetic resin composite material is mainly composed of synthetic leather-like fabric composite or fiber reinforced plastic (FRP), and has a great difference in appearance and texture as well as natural materials and their physical and chemical properties, Not only was it difficult to apply to high-end products, but it also contains various harmful substances, and has been ignored by health-conscious consumers.

특히, 최근 건강과 환경에 대한 관심이 높아지면서 식품이나 의류와 같이 신체에 직접 접촉되는 물품 뿐 아니라, 가구나 화분 등 일상생활용품은 물론 건축용 내장재에 이르기 까지 천연소재의 제품이 선호되는 추세이다.In particular, as interest in health and the environment has increased in recent years, products of natural materials have been preferred not only to articles directly contacting the body such as food or clothing, but also to everyday products such as furniture and flower pots, as well as interior materials for construction.

그러나 이러한 천연소재는 공급에 한계가 있고, 고가일 뿐 아니라, 이를 채취하는 과정에서 더욱 심각한 환경오염을 유발하는 등 그 적용에 있어서 많은 문제점을 가지고 있었다.However, these natural materials are limited in supply and expensive, and have many problems in their application, such as causing more serious environmental pollution in the process of collecting them.

본 발명은 전술한 문제점을 감안하여 창안한 것으로 화강암, 현무암 또는 맥반석 등의 자연석 분말과 산화마그네슘, 옥 및 백탄의 미세한 분말을 배합하여 혼합분말을 구성하고 여기에 불포화폴리에스테르수지를 첨가하여 분말 입자간의 접착이 이루어지도록 함으로써 강도와 성형성은 물론 식물이 활착가능한 생물친화성 또한 확보할 수 있도록 한 것이다.The present invention has been made in view of the above-described problems, by mixing natural stone powders such as granite, basalt or elvan, and fine powders of magnesium oxide, jade and white charcoal to form a mixed powder and adding unsaturated polyester resin to the powder particles. The adhesion between the liver is to ensure the strength and moldability as well as biocompatible biocompatible plants.

또한, 분말·수지혼합물에 휘발성 물질인 시너를 혼합하여 수작업을 통한 성형중에 분말·수지혼합물이 손에 달라붙지 않도록 함으로써 성형성을 개선하고, 맥반석, 옥 및 백탄 등에서 방사되는 원적외선을 통하여 사용자의 건강증진 효과도 얻을 수 있도록 하였다.
In addition, by mixing thinner, which is a volatile substance, with the powder and resin mixture, the powder and resin mixture is prevented from sticking to the hands during molding through manual operation, thereby improving moldability and user's health through far-infrared rays emitted from elvan, jade and white coal. Enhancement effect was also obtained.

본 발명의 상세한 구성을 첨부된 도면을 통하여 설명하면 다음과 같다.The detailed configuration of the present invention through the accompanying drawings as follows.

우선 도 1은 본 발명의 제조공정 흐름도로서, 동 도면을 통하여 알 수 있는 바와 같이, 본 발명은 원석 및 첨가재를 미세한 분말로 분쇄한 후, 이를 소정의 비 율로 혼합하고, 여기에 소정량의 합성수지를 혼합하여 소기의 형상으로 성형한 후 양생하는 과정을 거쳐 이루어지게 된다.First, Figure 1 is a manufacturing process flow chart of the present invention, as can be seen through the drawings, the present invention is to grind the raw materials and additives into a fine powder, and then mixed them in a predetermined ratio, a predetermined amount of synthetic resin After mixing to form a desired shape is made through a curing process.

본 발명에 사용되는 원석은 화강함, 현무암 또는 맥반석 등의 자연석으로서 각각의 특징을 간략하게 설명하면 다음과 같다.The gemstones used in the present invention are briefly described for each feature as natural stones, such as granite, basalt or elvan.

맥반석(麥飯石)은 화성암류중 석영반암에 속하는 암석으로서, 이산화규소와 산화알루미늄이 주성분이며, 이 밖에도 산화제2철을 비롯한 다양한 광물성분이 함유되어 있다.Elvan is a rock belonging to quartz rock in igneous rocks, and its main components are silicon dioxide and aluminum oxide, and it also contains various mineral components including ferric oxide.

맥반석은 원적외선을 다량으로 방출하는 특성을 가지고 있는데, 원적외선은 에너지의 전달특성이 우수하여 열선이라고도 불리우며 조사(照射) 대상체의 표면을 파괴하지 않고 물체의 내부까지 침투하여 물체를 구성하는 분자를 활성화하는 특징이 있다.Elvan has a characteristic of emitting a large amount of far infrared rays, which are called heat rays because of their excellent energy transfer characteristics, and penetrate to the inside of an object without destroying the surface of the irradiated object to activate molecules constituting the object. There is a characteristic.

이러한 원적외선을 생물체에 조사(照射)하게 되면 육성촉진, 세포활성화, 혈행촉진, 대사기능촉진 및 진통작용 등의 효과를 얻을 수 있어, 건강증진은 물론 피로회복 및 노화방지에도 탁월한 효과가 있는 것으로 알려져 있다.When irradiated with such an infrared ray, it is known that it is effective in promoting growth, cell activation, blood circulation, metabolic function, and analgesic effect. have.

한편, 본 발명에 있어서 원석과 분말상으로 혼합되는 첨가재로는 산화마그네슘, 옥 및 백탄을 들 수 있으며 각각의 특징을 간략하게 설명하면 다음과 같다.On the other hand, in the present invention, the additives mixed in the form of gemstones and powders include magnesium oxide, jade and white charcoal.

산화마그네슘(酸化magnesium)은 마그네슘과 산소의 화합물로서 마그네시아라고도 불리우며, 내화성이 뛰어나 건축용 내장재의 소재로 활용되고 있다.Magnesium oxide (magnesium oxide) is a compound of magnesium and oxygen, also called magnesia, has excellent fire resistance and is used as a material for building interior materials.

옥(玉)은 대표적인 장식용 광물로서 외관상의 아름다움 뿐 아니라, 다량의 원적외선을 방사하여 건강에 유익한 것으로 알려져 있다.Jade is a representative decorative mineral, which is known to be beneficial to health by radiating a large amount of far infrared rays as well as the beauty of appearance.

백탄(白炭)은 백회색 목탄의 일종으로서, 참숯이라고도 하며, 주로 떡갈나무나 졸참나무 등의 탄재를 저온의 돌가마에서 탄화시키고 마지막으로 가마 속에 다량의 공기를 보내어 수피(樹皮)나 탄의 일부를 연소시킨 다음 흙과 재로 덮어서 냉각소화시켜 제조되며, 대표적인 다공체(多孔體)로서 탈취 및 습도조절 등의 효과가 있다.White charcoal is a kind of white gray charcoal, also known as true charcoal. It mainly carbonizes charcoal such as oak and prunus oak in low temperature stone kiln, and finally sends a large amount of air into the kiln to make part of bark It is produced by burning and then cooling and extinguishing by covering it with soil and ash. As a representative porous body, it has effects such as deodorization and humidity control.

이러한, 원석 및 첨가재는 미세한 분말로 분쇄되어, 원석 50중량% 내지 60중량%, 산화마그네슘 10중량% 내지 20중량%, 옥 1중량% 내지 9중량% 및 백탄 20중량% 내지 30중량%로 혼합 및 교반되어 혼합분말을 구성하게 된다.These, gemstones and additives are pulverized into fine powder, mixed with 50% to 60% by weight of gemstone, 10% to 20% by weight of magnesium oxide, 1% to 9% by weight of jade and 20% to 30% by weight of charcoal. And it is stirred to form a mixed powder.

혼합분말이 충분히 교반되어 각각의 분말이 고르게 분포되면, 혼합분말 85중량% 내지 90중량% 및 불포화폴리에스테르수지 10중량% 내지 15중량%를 혼합, 교반하여 분말·수지혼합물을 구성하게 된다.When the mixed powder is sufficiently agitated and each powder is evenly distributed, 85 to 90% by weight of the mixed powder and 10 to 15% by weight of the unsaturated polyester resin are mixed and stirred to form a powder / resin mixture.

이후, 분말·수지혼합물을 소기의 형상으로 성형하여 제품을 완성하게 되는데, 성형 방법으로는 도 2와 같은 수작업을 통한 성형과 도 3과 같은 금형을 통한 성형을 들 수 있다.Thereafter, the powder-resin mixture is molded into a desired shape to complete the product. Examples of the molding method include molding through a hand as shown in FIG. 2 and molding through a mold as shown in FIG.

수작업을 통한 조형(造形)시 분말·수지혼합물이 손에 달라붙게 되므로, 이를 방지하기 위하여 휘발성 물질인 시너(thinner)를 첨가하게되며, 그 첨가비는 분말·수지혼합물 95중량% 내지 99중량%와 시너 1중량% 내지 5중량%로 하는 것이 바람직 하다.When molding by hand, the powder / resin mixture sticks to the hands, so to prevent this, thinner, a volatile substance, is added, and the addition ratio is 95 to 99% by weight of the powder / resin mixture. It is preferable to set it as 1 to 5 weight% of the thinner.

시너는 휘발성이 매우 강하므로, 일단 성형이 완료되면 양생되는 과정에서 모두 휘발하게 되어, 최종단계에서는 잔류하지 않게 된다.Since the thinner is very volatile, once the molding is completed, all of the thinner volatilizes, and does not remain in the final stage.

또한, 금형을 통한 성형은 금형에 분말·수지혼합물을 투입하고 상형 및 하형을 결합, 압착하여 성형한 후 탈형하는 과정을 거치게 되는데, 이때 금형에 파라핀 등의 이형제를 도포하거나, 전술한 분말 중 가장 미립의 것을 미량 살포함으로써 탈형이 용이하게 할 수도 있다.In addition, the molding through the mold is a powder, resin mixture is put into the mold, and the upper and lower molds are combined, pressed and molded to demould, and at this time, a mold release agent such as paraffin is applied to the mold, or most of the powders described above. Demolding can also be made easy by spraying a trace amount of fine particles.
